Option Description
Memory Sets the speed of the system memory. You can select Maximum Performance,
Frequency Maximum Reliability, or a specific speed.
Turbo Boost Enables or disables the processor to operate in the turbo boost mode. This option
is set to Enabled by default.
Energy Efficient Enables or disables the Energy Efficient Turbo option.
Turbo
Energy Efficient Turbo (EET) is a mode of operation where a processor's core
frequency is adjusted to be within the turbo range based on workload.
C1E Enables or disables the processor to switch to a minimum performance state when
it is idle. This option is set to Enabled by default.
C States Enables or disables the processor to operate in all available power states. This
option is set to Enabled by default.
Collaborative CPU Enables or disables the CPU power management option. When set to Enabled, the
Performance CPU power management is controlled by the OS DBPM and the System DBPM
Control (DAPC). This option is set to Disabled by default.
Memory Patrol Sets the memory patrol scrub frequency. This option is set to Standard by default.
Scrub
Memory Refresh Sets the memory refresh rate to either 1x or 2x. This option is set to 1x by default.
Rate
Uncore Frequency Enables you to select the Processor Uncore Frequency option.
Dynamic mode enables the processor to optimize power resources across the
cores and uncore during runtime. The optimization of the uncore frequency to
either save power or optimize performance is influenced by the setting of the
Energy Efficiency Policy option.
Energy Efficient Enables you to select the Energy Efficient Policy option.
Policy
The CPU uses the setting to manipulate the internal behavior of the processor and
determines whether to target higher performance or better power savings.
Number of Turbo
Boot Enabled
Cores for
Processor 1
Controls the number of turbo boost enabled cores for processor 1. The maximum
number of cores is enabled by default.
Monitor/Mwait Enables the Monitor/Mwait instructions in the processor. This option is set to
Enabled for all system profiles, except Custom by default.

NOTE: This option can be disabled only if the C States option in the Custom
mode is set to disabled.
NOTE: When C States is set to Enabled in the Custom mode, changing the
Monitor/Mwait setting does not impact the system power or performance.
